Error in A/B testing for

Hello all :slight_smile:

I’m all set to do the above project and this is the error message I got even before starting, i.e. without me doing any of the project tasks. I’m not really sure how to deal with this one. I’ve had a look at the walkthrough video and the first lines are exactly the same.
Any idea?
Thank you so much for your help!

Traceback (most recent call last):
File “”, line 1, in

File “/var/codecademy/runner_contexts/python/”, line 1, in
import StringIO
ModuleNotFoundError: No module named ‘StringIO’

The project is here

It looks like it’s on Codecademys end where the problem is - the error is pointing at a library they’re using for the module.

I’m getting the same message when I go to that project, despite already completing it.

In the ‘get unstuck’ tab there’s an option for reporting bugs (i’ve sent one as well).


Thank you! Did you actually manage to complete it?

Hm. Yes report the bug. Also, I’ll report it on my end.
I’ve not looked at that project in awhile.


A little while ago ( before the bug ), but yeah.
